Defending champion Judd Trump produced a sensational 147 break on his way to a 5-3 win over Tian Pengfei in the third round of the China Open.
Trump, who secured an emphatic 5-0 win over Eden Sharav in the previous round, registered the third maximum of his career in the fifth frame to open up a 4-1 advantage.
Tian reduced the deficit to 4-3 with breaks of 60 and 63, but Trump held his nerve to close out the match in the eighth frame.
Trump told the World Snooker website: "I've had a lot of good chances recently and it was nice to make a 147 on the TV table. The next frame I potted a good ball to get in.
"I then split the pack well but unfortunately the red went in. I probably would have made another century if that didn't happen, you need a bit of luck in those situations.
"After that he played well and things like that can change games, so I'm happy to get through."
Mark Williams battled back from 4-1 down to defeat John Higgins 5-4 in a thrilling contest.
The two-time world champion won the sixth frame before reeling off breaks of 66, 60 and 79 to edge out Higgins.
Williams will face Shaun Murphy, a 5-1 winner against Michael White, in the quarter-finals.
World champion Mark Selby edged a tense final-frame decider against Andrew Higginson and will next face Stephen Maguire, a comfortable 5-1 winner over Daniel Wells.
Mark Joyce was unable to follow up his impressive win over Ronnie O'Sullivan as he slipped to a 5-3 defeat against Ding Junhui.
The Chinese player will take on Kyren Wilson, who saw off former world champion Stuart Bingham 5-2, for a place in the semi-finals.
Trump's next opponent is Hossein Vafaei, who overcame Rory McLeod 5-3 earlier in the day.
